The impact of the experimental route of challenge on the host responses and pathogenesis of the Canadian Delmarva (DMV/1639) infectious bronchitis virus infection in laying chickens

Mohamed S. H. Hassan et al.

Summary: Infectious bronchitis virus (IBV) infection can cause respiratory, renal, and reproductive diseases in chickens. This study investigated the impact of adding the trachea as a potential route of viral entry to the oculo-nasal infection. The results showed differences in clinical signs, egg production, and tissue lesions between different groups.

Efficacy of Commercial Infectious Bronchitis Vaccines against Canadian Delmarva (DMV/1639) Infectious Bronchitis Virus Infection in Layers

Mohamed S. H. Hassan et al.

Summary: Vaccination is the most important way to control infectious bronchitis in chickens. This study evaluated the efficacy of existing vaccines in Canada against a specific strain of the virus. The vaccinated chickens showed improved egg production, immune response, and reduced viral load in target organs, indicating that the vaccination program used in this study was effective in minimizing the impact of the virus.

Host immune response to infectious bronchitis virus Q1 in two commercial broiler chicken lines

Basim Manswr et al.

Summary: This study showed differences in immune responses and viral loads to infectious bronchitis virus infection among different commercial broiler chicken lines, which may be influenced by levels of maternal antibodies, growth rates, and other inherent host genetic factors.
